Hello guys and girls!
I've stumbled into this problem with my music software months ago, but didn't have an account here then to ask for help. Every time I try to save a file after working on my composition for a few minutes, I get the error message saying "Cannot create a file when that file already exists." On the Finale forum, it recommends using "Save As...," but occasionally I get the meesage saying "Cannot rename file" and my file doesn't save.
Also when trying other methods to save files which initially work, such as saving in a different folder/subfolder from the original, I get messages with "finsave.tmp" and "Access is denied" which I can't recreate conveniently. I've used Finale 2012 (yeah, have to mention the year and not hide it this time for extra information) for over 3 years now and only had this problem recently (relative to the length of time I've used it). What's your solution to this predicament?
